BRACKET FOR CAR-DOORS.

Specification of Letters Patent.

PatentedJuly I8, 1916.

Application led April 17, 1916. Serial N o. 91,599.

My invention relates to brackets for sup-,

porting the sliding doors of freight cars, and particularly to bracketsin which antifriction rollers are employed.

The object of my invention is to provide a bracket having a conveXedanti-friction roller or wheel upon which the door is reciprocablymounted, and to otherwise construct said bracket so that when the doorhas been moved inward by the engagement of a flange depending from thelower edge thereof with said roller said flange will be held out ofengagement with said roller'and not interfere with the rotation thereof.This I accomplish by the means hereinafter fully described, and asparticularly pointed out in the claims.

In the drawings: Figure 1 is a side view of my invention. Fig. 2 is afront elevation of the sama Fig. 3 is a vertical transverse sectiontaken on dotted line 3 3, Fig. 2.

Referring to the drawings, A represents a supporting-plate which issecured to the side of a car by rivets c that extend through one leg ofthe lower end of a vertically disposed angle-iron post Z) and throughthe web of a channel-beam side-sill B below the horizontal plane of thedecking C of the car. The decking. C is suitably supported upon theupper flange of channel-beam B, and at the door-way of the car the endsof this decking project beyond the vertical plane of said channel-beamto form the sill of the door, the sides of which latter are formed bythe outwardly projecting legs of the post b, whose outer edges are,preferably, fiushwith the outer edge of the door-sill.

Two corresponding arms D, D, project outwardly and, preferably, upwardat a suitable angle from said plate A'and have their ends connected by asuitable transverse vertically disposed front-plate E, the upper edge ofwhich projects upward above arms D, D, a'suitable distance. Thisfront-plate E is parallel to the side of the car, and midway betweenarms D, D, it is provided with, a tubular boss J, the axis of which isat right angles to plate A and the bore of which ispreferably, square incross-section Y and projects'to the rear of plate E a distance greaterthan it projects to the front of said plate. The portion thereofextending to the rear is cylindrical and has a roller F journaledthereon. This roller may be made dished, as shown in Fig. 3 of thedrawings, or it may be made solid and with the side thereof next the carconveXed. The roller is retained in position by means of a bolt Gr, thebarrel of which is made square to fit into the square bore of boss J andit is secured in said boss by a suitable rivet or pin H thatis passedthrough suitable apertures in the outwardly projecting portion of bossJ. The rear end of bolt G is provided with a head g whose diameter isgreater than that of said boss, and this head is seated in thecountersunk edges fof the inner end of the central opening of roller F.

A sliding door I 'of any suitable construction is employed to close thedoor-way of the car, and the lower edge 'of this door is provided with ametallic tread K consisting, preferably, of a Z-bar having comparativelylong flanges. The web of this Z-bar tread is attached directly to thelower edge of the door in any suitable manner and has its outer flange cprojecting upward and lapping against the lower margins of said door,and its inner flange 7c projecting downward in a vertical plane parallelto but slightly in front of that of the inner surface of the door. Thisdoor I is supported by suitable brackets so as to slide back and forthin front of the door-way and so that its lower edgewill pass in front ofthe outer ends of decking C forming the door-sill, and when said door ismoved toward its closed. position the end of the tread will fit upon theroller, and at the same time flange 7 thereof will come in contact withthe conveXed rear side of roller F, and it and door I will be pushedrearward toward the adjacent side of the car 'so as to tightly close thedoor-way, and when lugs they may be dispensed with. The upper edges ofarms D, D, are, preferably, flanged outward and the rear sides of lugs Lmay be provided with lins to strengthen them, and between the base oflugs L (which is below the lower edge of flange 7c of the Z-bar treadK), and the outer ends of said. arms, the latter may have upwardlyprojecting integral wings to which the end edges of frontplate E may beconnected in such manner as to reinforce said front-plate.

vWhat I claim as new is:

1. In a car, the combination with a door having a longitudinal flangedepending from its lower edge, of a bracket comprising asupporting-plate, an arm projecting therefrom, a front-plate supportedby and projecting above the same, and a roller that supports said doorhaving its side nearest the adjacent side of the car convex and adaptedto be engaged by said flange, and means for journaling said roller thatprojects rearwardly from said wall and is provided with a head thatretains said roller in position and has its rear end convexed and isengaged by said flange as the latter passes the axis of said roller.

2. In a car, the combination with a door having a longitudinal flangedepending from its lower edge, of a bracket comprising asupporting-plate, an arm projecting outward therefrom, a front-platesupported by and projecting above the same, a tubular boss made integraltherewith and having its axis at right angles thereto, a rollerjournaled upon said boss upon which said door travels which has its sidenearest the car convexed and adapted to be engaged by said flange, and abolt seated in the bore of said boss that has a head on its inner endthe crown of which is convexed and which retains said roller on saidboss and is en gaged by said flange as the latter passes the axis ofsaid roller.

3. ln a car, the combination with a door having a longitudinal flangedepending from its lower edge, of a bracket comprising asupporting-plate, an arm projecting outward therefrom, a front-platesupported by and projecting above the same, a tubular boss made integraltherewith and having its axis at right angles thereto, a rollerjournaled upon said boss upon which said door travels which has its sidenearest the car convexed and adapted to be engaged by said flange, and a`bolt seated in the bore of said boss that has a head on its inner endthe crown of which is convexed and which is seated in the rabbeted edgeof the inner side of the central opening of said roller with itsconvexed crown flush with the convexity of the same and is engaged bysaid flange as the latter passes the axis of said roller.

Il. 1n a car, the combination with a door having a longitudinal flangedepending from its lower edge, of a bracket comprising asupporting-plate, an arm projecting therefrom, a front-plate supportedby and projecting above the same, a lug projecting upward from said armbetween said frontplate and supporting-plate, and a roller having itsside nearest the adjacent side of the car convex, and means forjournaling said roller that projects rearwardly from said wall and isprovided with a head that retains said roller in position and has itsrear end convexed and is engaged by said flange as the latter passes theaxis of said roller.

5. In a car, the combination with a door, a longitudinal Z-bar treadsecured to the lower edge thereof and having a flange dependingtherefrom, of a bracket comprising a suitable supporting-plate, parallelarms projecting outward therefrom, a front-plate connecting the outerends of said arms and having an integral boss the horizontal axis ofwhich is at right angles thereto, a roller j ournaled on the innerportion of said boss and having its inner side convexed and the inneredge of its central opening rabbeted, and a bolt seated in the bore ofsaid boss and having a head whose crown is convexed and is adapted to beseated in said rabbeted head with its crown flush with the convexity ofsaid roller and is engaged by said flange as the latter passes the axisof said roller.
